Reduced power messages usually come from one of two issues:
A major electrical issue with the vehicle's computer- this could be rodent damaged wiring, a failed PCM, an internally shorted charging system, etc.
The vehicle is overheating- this could be a stuck closed thermostat or low coolant.
It's very possible. I have also seen a handful of vehicles that did not have antifreeze in the coolant. This is common in areas that don't typically get very cold- mechanics or body shops skimp on the antifreeze and the coolant will freeze in the radiator causing the engine to overheat.
Was your heater working when the reduced power message came on?
